[RE-wrenches] Adding battery to grid tie

[Zeke Yewdall]

That's actually what I prefer doing on most systems, to have exactly the
monitoring I want, at higher precision than the AIO's give, and also
independent of the AIO's server, wherever that may be.   And accessible on
the LAN, with data storage, if their internet blips out too.  But, not all
customers can take the cost of a good egauge setup, which tends to run at
least $2k if you start adding DC ct's and voltage transducers to monitor
the MPPT inputs.  $1k even for a basic AC monitoring setup.
